Where do you get that kind of information when you are transferring files between
Macs via Ethernet? I too transfer files between my PPC 6500 & 2300 (I assume you
go both ways: G3 to 2300 and vice versa, too?) and have been less than overjoyed
at the transfer rate. Then again I am using the built-in 10bT card on the Dock
Plus which limits transmission to a maximum of 10mb/sec. My understanding is that
even with a 100bT Nubus card, Nubus limits transmission speed to around 33mb/sec
anyway. I have never clocked the actual rate of transfer, so I do not know if I
am just impatient or justifiably upset.
Now, I just noticed the transfer rates everyone is quoting: 8Kb, 25Kb, 200Kb,
300Kb, 500Kb. The only impressive number here is 500Kb and that is by Local Talk
standards which is a maximum transfer rate of 230.4Kbps. So, I think you guys are
getting your numbers from some strange place (or not). 10bT Ethernet is quite a
bit faster than 230.4Kbps (which is why Local Talk isn't the industry standard),
which is about the same as 1.8 megabits. Whereas 10bT is 10 megabits or 1280Kb,
100bT (100 megabits) is 12,800Kb or 12.6MB. Wow!
So, you can see that when it comes to pure Ethernet transfer rates between two
Macs speaking the same language, that 33Mhz bus is having a stifling effect on
Steffen's Duo's ability to achieve the the maximum rate possible by well over 3
quarters of it's technical capacity (assuming he's using a 10bT card, it's far
worse if he's using a 100bT card in the Dock). While I am not certain of the
intricacies of the cable modem interface, I would say that the introduction of a
sluggish piece of software like a browser to interpret and handle the data flow
puts that 25Kbs rate well into the likely range of the Duo's maximum capability
vis-a-vis internet downloading.
